CERT/CC recommended keeping chain codes confidential and avoiding reliance on hardened key derivation to isolate signer shares until Fireblocks corrects its mpc-lib library implementation.

CERT/CC published advisory VU#701544 on October 26, 2026, identifying a hardened-derivation vulnerability in Fireblocks' mpc-lib library under CVE-2026-90975.

The SP1 soundness flaw affected native Rust verification in sp1_hypercube, sp1_prover, and sp1_sdk versions 6.0.0 through 6.8.0

A high-severity soundness bug in Succinct's SP1 zero-knowledge proving system exposed Succinct's mainnet Prover Network to invalid execution proofs from third-party provers

On-chain Solidity verifiers for Groth16 and Plonk checks and applications whose proof aggregation ended in Groth16 or Plonk proofs were unaffected by SP1's high-severity soundness bug

Succinct deployed the version 6.8.1 patch for SP1's soundness bug to the mainnet Prover Network, requiring no configuration changes from users requesting network proofs

An attacker could exploit SP1 by supplying proof data with mismatched size labels, causing the native Rust verifier to accept an invalid proof

Succinct stated in GitHub security advisory GHSA-p7v2-jjv3-8p8f that its mainnet Prover Network was the only known deployment affected by a high-severity soundness bug in SP1's proving system

Succinct advised users running native Rust verifiers in SP1 who accept proofs from untrusted provers to upgrade their software to version 6.8.1

Groth16 and Plonk proof checks in SP1 remained safe because they used wrapped proofs with fixed shapes that bypassed prover-controlled tensor formats

SP1 stores multidimensional data in Tensors, where SP1's native Rust verifier failed to check whether the number of stored elements matched the product of the tensor's declared dimensions

Succinct released version 6.8.1, which patched a high-severity soundness bug in SP1, on September 24, 2026, 17 days before publishing GitHub security advisory GHSA-p7v2-jjv3-8p8f on October 11, 2026
